Headache and MTHFRT677T Genotype in a Young Woman - Clinical Case
Bibliographic record
Abstract
Introduction:The MTHFRC677T polymorphism is involved in several pathologies.Objectives: We report one case of headache associated with the MTHFR T677T genotype in a woman.Observation: A 39-year-old woman was admitted in neurology department on March 12, 2012 for headaches with feet and hands parathesia for several months.The physical examination had noted a decrease in osteotendinous reflexes and an abolition of the plantar cutaneous reflex.Hamilton's 17-item depression score was 7. In the etiological investigation of probable polyneuropathy, homocysteine was 88.39 μmol/l (standard < 15 μmol/l), folates 2.34 nmol/l (standard ≥ 11 nmol/l) and vitamin B 12 132 pmol/l (standard ≥ 147 pmol/l).The aetiological investigation of this hyperhomocysteinemia revealed an MTHFRT677T genotype. Conclusion:The MTHFRT677T genotype is associated with a variety of manifestations ranging from metabolic (B 12 deficiency), headache and polyneuropathies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
